working with collections.

Modifier and Type | Method and Description |
---|---|
static Ordering<Object> |
Ordering.allEqual()
Returns an ordering which treats all values as equal, indicating "no ordering." Passing this
ordering to any stable sort algorithm results in no change to the order of elements.
|
static Ordering<Object> |
Ordering.arbitrary()
Returns an arbitrary ordering over all objects, for which
compare(a, b) == 0 implies
a == b (identity equality). |
<U extends T> |
Ordering.compound(Comparator<? super U> secondaryComparator)
Returns an ordering which first uses the ordering
this , but which in the event of a
"tie", then delegates to secondaryComparator . |
static <T> Ordering<T> |
Ordering.compound(Iterable<? extends Comparator<? super T>> comparators)
Returns an ordering which tries each given comparator in order until a non-zero result is
found, returning that result, and returning zero only if all comparators return zero.
|
static <T> Ordering<T> |
Ordering.explicit(List<T> valuesInOrder)
Returns an ordering that compares objects according to the order in which they appear in the
given list.
|
static <T> Ordering<T> |
Ordering.explicit(T leastValue,
T... remainingValuesInOrder)
Returns an ordering that compares objects according to the order in which they are given to
this method.
|
static <T> Ordering<T> |
Ordering.from(Comparator<T> comparator)
Returns an ordering based on an existing comparator instance.
|
static <T> Ordering<T> |
Ordering.from(Ordering<T> ordering)
Deprecated.

|
<S extends T> |
Ordering.lexicographical()
Returns a new ordering which sorts iterables by comparing corresponding elements pairwise until
a nonzero result is found; imposes "dictionary order".
|
static <C extends Comparable> |
Ordering.natural()
Returns a serializable ordering that uses the natural order of the values.
|
<S extends T> |
Ordering.nullsFirst()
Returns an ordering that treats
null as less than all other values and uses this to compare non-null values. |
<S extends T> |
Ordering.nullsLast()
Returns an ordering that treats
null as greater than all other values and uses this
ordering to compare non-null values. |
<F> Ordering<F> |
Ordering.onResultOf(Function<F,? extends T> function)
Returns a new ordering on
F which orders elements by first applying a function to them,
then comparing those results using this . |
<S extends T> |
Ordering.reverse()
Returns the reverse of this ordering; the
Ordering equivalent to Collections.reverseOrder(Comparator) . |
static Ordering<Object> |
Ordering.usingToString()
Returns an ordering that compares objects by the natural ordering of their string
representations as returned by
toString() . |
